Ingredients
- •1 medium butternut squash, peeled and cubed (about 4 cups)
- •1 medium onion, chopped
- •2 garlic cloves, minced
- •1 tablespoon olive oil
- •1/2 teaspoon ground cinnamon
- •1/2 teaspoon ground nutmeg
- •1/4 teaspoon cayenne pepper
- •4 cups vegetable broth
- •1 cup cooked chestnuts, chopped
- •1/2 cup heavy cream
- •Salt and pepper to taste
- •4 slices of bread, diced into cubes (for croutons)
- •2 tablespoons butter
- •1 tablespoon fresh lemon thyme leaves
- •1 teaspoon lemon zest
Instructions
- 1
Preheat your oven to 400°F (200°C). Spread the cubed butternut squash on a baking sheet, drizzle with 1 tablespoon olive oil, and season with salt and pepper. Roast for 25-30 minutes, or until tender and slightly caramelized.
- 2
While the squash is roasting, heat a large pot over medium heat. Add a drizzle of olive oil, then sauté the chopped onion until soft and translucent, about 5-7 minutes. Add the minced garlic and sauté for another minute until fragrant.
- 3
Stir in the ground cinnamon, nutmeg, and cayenne pepper, cooking for 30 seconds to toast the spices.
- 4
Add the roasted butternut squash, vegetable broth, and chopped chestnuts to the pot. Bring the mixture to a boil, then reduce heat and simmer for 10-15 minutes to allow the flavors to meld.
- 5
Using an immersion blender (or transferring in batches to a countertop blender), blend the soup until smooth and creamy. Stir in the heavy cream and season with salt and pepper to taste. Keep warm on low heat while preparing the croutons.
- 6
To make the croutons, melt the butter in a skillet over medium heat. Add the bread cubes, tossing to coat in the butter. Sprinkle with lemon thyme leaves and lemon zest, and cook until the croutons are golden and crisp, about 5-7 minutes.
- 7
Serve the soup hot with a handful of Lemon Thyme Croutons on top. Optionally, garnish with additional thyme leaves or a drizzle of cream for presentation.

Frequently Asked Questions
Q: Can I use frozen butternut squash instead of fresh?
A: Yes, you can use frozen butternut squash as a convenient alternative. There is no need to thaw it beforehand; simply roast it directly from frozen on a baking sheet. However, roasting time may be slightly shorter, so check for tenderness after 20 minutes.
Q: What can I substitute for chestnuts if I can’t find them?
A: If chestnuts are unavailable, you can use hazelnuts, walnuts, or even canned white beans for a similar creamy texture. Keep in mind that nuts will add a different flavor profile, while beans provide a more neutral taste.
Q: Can I make this soup dairy-free?
A: Yes, you can make this soup dairy-free by substituting the heavy cream with coconut milk or a plant-based cream alternative. The flavor will shift slightly, with coconut milk adding a subtle sweetness, but the soup will still be delicious.
Q: How can I prevent the soup from being too spicy?
A: If you’re sensitive to spice, reduce or omit the cayenne pepper. You can always add a small pinch at the end of cooking to adjust the heat to your liking.
Q: What’s the best way to store leftovers?
A: Allow the soup to cool completely, then transfer it to an airtight container. It can be stored in the refrigerator for up to 4 days or in the freezer for up to 3 months. Reheat gently on the stovetop, adding a splash of broth or water if the soup has thickened.
Q: Can I make the croutons ahead of time?
A: Yes, you can make the croutons a day in advance. Let them cool completely, then store them in an airtight container at room temperature. Reheat briefly in a skillet or oven to restore crispness before serving.
Q: What are some serving variations for this soup?
A: For added texture, garnish with toasted pumpkin seeds or a sprinkle of crispy bacon bits. You can also swirl in a dollop of Greek yogurt or sour cream for extra creaminess. For a vegan option, skip the cream and top with a drizzle of olive oil and fresh herbs.
